Remove deprecations for methods taking KClass? [DATAMONGO-2395]

Johan Haleby opened DATAMONGO-2395 and commented

Hi, 

In Spring Data MongoDB 2.1.x I have code that looks like this:

fun createCollectionsIfNotExists(vararg entityClasses: KClass<*>) = entityClasses.forEach { entityClass ->
 if (!mongo.collectionExists(entityClass)) {
 mongo.createCollection(entityClass)
 }
}
createCollectionsIfNotExists(MongoDTO1::class, MongoDTO2::class, MongoDTO3::class, MongoDTO4::class)

In 2.2 "collectionExists" and "createCollection" has been deprecated in favor of reified counterparts.  However invoking the reified methods is difficult if you just have "KClass"  (see https://stackoverflow.com/questions/55399737/calling-a-fun-with-reified-type-parameter-if-you-just-have-a-kclass-object). Is there a recommended approach to deal with situations like the one I have in 2.2 or could both method variants be retained (i.e. both KClass and the reified version)?
